Abstract
The utility model discloses a composite cable, which comprises a cable core and a jacket. The jacket is used to wrap the cable core, the cable core comprises a signal transmission unit and a power supply unit at one time, the cable also comprises a filling piece, the filling piece is arranged between the signal transmission unit and the power supply unit, which provides a well supporting performance to the composite cable by adding filling piece inside the cable core, makes the composite have a stronger persistence performance, the structure is firm and uneasy to distort.
Description
Technical field
The utility model relates to a kind of transmission medium, is meant the composite cable of a kind of transmission of electric signals simultaneously and power electricity especially.
Background technology
In the photoelectricity transmission field, cable is a kind of very important transmission medium, has been widely used in the signal transmission technology field at present.
Growing along with optical communication, also more and more higher to the requirement of cable, both required cable transmission of electric signals and power electricity simultaneously, require firm in structure again and signal and power supply can not interact.
Existing composite cable is simultaneously transmission of electric signals and power just, but only be the signal transmission unit that to be used for transmission of electric signals and the power supply unit simple twist that is used to transmit the power electricity is in the same place, such structure is too simple, make composite cable can not bear external force, easy deformation can't satisfy composite cable drag performance demands.
In addition, because signal transmission unit and power supply unit in the existing composite cable are coated in the sheath simply, and signal transmission unit and power supply unit are to twist together merely, the electromagnetic wave that produces when like this, signal transmission unit and power supply unit are worked simultaneously can cause the interference on the signal.
Summary of the invention
In view of this, the utility model provides a kind of composite cable, strengthens the drag performance; And can further improve the shielding properties of composite cable.
The composite cable that the utility model provides comprises cable core and sheath, and described cable core comprises signal transmission unit and power supply unit simultaneously, and described cable core also comprises: filling member, and between signal transmission unit and power supply unit.
Further comprise between described cable core and the described sheath: screen.
Described screen is: foil shielding layer; Or woven shield; Or foil shielding layer and woven shield, and foil shielding layer is between woven shield and described sheath.
Described woven shield adopts the screen with count of metal wire knitted.
Described count is more than 60%.
Each unit in the described cable core is that the center outwards distributes with the round dot of composite cable cross section, and one of them unit is positioned at the center, and remaining element is positioned at around this unit, and described filling member is between center cell and peripheral cell.
The material of described filling member is for strengthening sand or polyethylene.
In the utility model, composite cable comprises cable core and sheath, sheath is used to coat cable core, cable core comprises signal transmission unit and power supply unit simultaneously, and this cable core also comprises filling member, and this filling member is between signal transmission unit and power supply unit, provide the good supporting performance by in cable core, increasing filling member for composite cable, make composite cable have stronger drag performance, firm in structure, not yielding.
In addition, by between cable core and sheath, increasing screen, make composite cable can shield interference signal, has very strong shielding properties, improved the transmission performance of signal, make signal transmission unit and power supply unit to work simultaneously, alternate power line and digital cable are not only saved cost but also make things convenient for installation.
Description of drawings
Fig. 1 is the utility model example structure schematic diagram.
Embodiment
In the utility model, composite cable comprises cable core and sheath, and sheath is used to coat cable core, and cable core comprises signal transmission unit and power supply unit simultaneously, and this cable core also comprises filling member, and this filling member is between signal transmission unit and power supply unit.The general employing of filling member has certain intensity and is easy to material processed, as strengthening sand, polyethylene etc.By in cable core, increasing filling member for composite cable provides the good supporting performance, make composite cable have stronger drag performance, firm in structure, not yielding.
Further, further comprise screen between the sheath of coating cable core and the cable core, this screen can be foil shielding layer or woven shield or foil shielding layer and woven shield.When screen comprises foil shielding layer and woven shield, composite cable have outer in be followed successively by sheath, woven shield, foil shielding layer, cable core.Woven shield can adopt metal knitted one-tenth to have the screen of certain count, and count can be decided according to desired shield effectiveness, can adopt the count more than 60% usually.By between cable core and sheath, increasing screen, make composite cable can shield interference signal, have very strong shielding properties, improve the transmission performance of signal.
Fig. 1 is the utility model example structure schematic diagram, as shown in Figure 1, the composite cable that present embodiment provides comprises cable core and oversheath, wherein, cable core comprises signal transmission unit 4, power supply unit 6 and filling member 5, and each unit in the cable core is that the center outwards distributes with the round dot of composite cable cross section, and a power supply unit 6 is positioned at the center, remaining element (comprising signal transmission unit 4 and power supply unit 6) is positioned at around this power supply unit, and filling member 5 is between center cell and peripheral cell.Signal transmission unit 4 is used for transmission of electric signals, and power supply unit 6 is used to transmit power.Oversheath comprises foil shielding layer 3, woven shield 2 and sheath 1 from inside to outside successively.Woven shield 2 adopts certain count to be woven in the outside of foil shielding layer 3.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from spirit and scope of the present utility model.Like this, if of the present utility model these are revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and modification interior.
